Application December29, 1942, Serial No. 470,501 3 claims.- (01. 251-18) The presentinvention relates to new and useful improvements in multi-way valves,particularly for controlling the flow of pulverized coal to burners,although that the device may be used for any other purmay be foundadapted.

The primary object of the invention is to provide, in a manner ashereinafter set forth, a valve of the character described which will beselfcleaning, whereby the accumulation of material between thestationary and moving parts will be it will be understood, ofcourse,.:-.

prevented, thus assuring free operation at all times.

' Another very important object of the invention is to provide a valveof the aforementioned character comprising a novel construction, forpreventing leakage. 5

Other objects of the inventionare to provide a valve of the characterset forth which will be comparatively simple in construction, strong,durable, highly efllcient and reliable use, compact, and. which may bemanufactured at low cost.

All of the foregoing, and still further objects and advantages of theinvention will become ap-. parent from a study of the followingspecification, taken in connection with the accompanying drawingswhereinlike characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in front elevation of a valve constructed in vention.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical sectional view, taken substantially on the line3-3 of Figure 1. Figure 4 is a view in horizontal section, takensubstantially on the line 4-4 of Figure 1.

The outletsb are aligned with the branches 5 I of the intake manifold 4for communication therewith. 1

Journaled for swinging movement on the lower stud bolt 3 and slidablyengaged with the inner face of the plate 2 is a substantially segmentalvalve member 1 which controls communication between the outlets 6 andthe branches I of the intake manifold l. The swinging valve member I hasformed therein an opening or port 8 for. registry. with either of thealigned members i and 6. An operating handle 9 projects from the freeend of the valve member I.

Loosely mounted on the stud bolts 3 between the plate I and the valvemember 1 is a substantially triangular intermediate plate It. Coilsprings ii on the stud bolts 3 yieldingly urge the Figure 6 is a view inside elevation of another form of the invention.

Referring now to the drawings inidetail, and to Figures 1 to 5,inclusive, thereof, in particular, it will be seen that referencenumerals l and 2 designate, espectively, substantially triangularmetallic fro t and back plates of suitable metal. shouldered stud bolts3 secure the plates i and 2 together in spaced, opposed relatio Mountedon the plate I is an intake manifold I, the branches 5 of which extendthrough' said plate.

plate It against the valve member 1 and said valve member 1 against theplate 2. The plate It has formed therein' openings l2 which are alignedwith the outlets 6 and into which the branches 3 of the intake manifold4 project, as illustrated to advantage in Figure 4 of the drawings. Itwill be observed that there is suflL cient clearance or space betweenthe walls of the openings l2 andthe intake manifold branches 5 to permitthe plate It to move slightly in any direction. Resilient,longitudinally extensible sealing rings l3 prevent leakage from theintake manifold branches 5 between the plates l and ill. l

a It is thought that the operation of the valve will be readily apparentfrom a consideration. of the foregoing. Briefly, with the swinging valvemember 1 in its intermediate or vertical position, as shown in thedrawings, both of the outlets 3 'are out of communication with themanifold branches I and the valve is closed. To cause the pulverizedcoal to flow to either of the burners, the valve member 1 is simplyswung, through the medium of the operating handle 9', in th correctdirection to align the port 3 with the proper outlet 3 and the correctbranch ofthe intake manifold 4. The floating mounting of theintermediate plate i 0 and the sliding mounting of the valve member 1 onthe stud bolts 3permits such movement of these parts when the valve isoperated as will prevent the accumulation of coal dust and other matter,which accumulation frequently causes valves in use at present to stickand to In the embodiment illustrated in Figures 6 and plates I4 and IIIare conthe bolts it between the plates l4 and i5.

Mounted on the plate ll is an intake manifold l8. Outlets it are mountedon the plate l5 for faces of the swinging valve members 20' accommodatethe end portions of the coil springs 2 I Male and female tubes 23 and24, respectively, are mounted on the valve members 20' for alignmentwith either of the outlets l9. suillcient play between the male andfemale tubes 23 and 24 to permit independent movement of the valvemembers 20'. Encircling the tubes 23 and 24 and extending between thevalve members 20' is a resilient, extensible sealing ring 25 forpreventing leakage at this point.

Rising from the free ends of the members 20' Loosely mounted between thelugs 28 is an operating handle 21' for the valve members 20. Pins 20 inthe lower end portion of the operating handle 21 are loosely engaged inthe apertures in the 1118s 2'.

In operation, the swinging valve members 20' are actuated through themedium of the handle 21 for establishing communication between either ofthe outlets l8 and the manifold it through the tubes 23 and 24. Theloose pivotal and sliding mounting of the valve members 20? on thelowermost spacer ll permits limited inswinging valve dependent movementof said valve members when the device is operated, whereby theaccumulation of matter between the relatively stationary and.

moving parts will be prevented.

It is believed that the many advantages of a Y valve constructed inaccordance with the present invention will be readily understood, andalthough preferred em diments of the device are as illustrated anddescribed, it is tobe understood that further modifications and changesin the details of construction may be resorted to which will fall withinthe scope of the invention as claimed. 7
